Banana Oatmeal Cookies with Chocolate Chips and Walnuts, an easy homemade oatmeal cookie recipe! These Banana Oatmeal Cookies are the best, crispy on the outside and soft and chewy on the inside, and loaded with banana, oats, chocolate chips, and nuts.
These Banana Oatmeal Cookies are perfect if you’re looking for something a little different than the standard oatmeal raisin cookies, or the standard overly gooey banana cookie. These cookies are full of oats, banana, chocolate chips, and walnuts and the perfect combo of crispy on the outside and soft and chewy on the inside. I’ve been on a bit of a banana and chocolate chip fixation lately so these cookies were the perfect fit.
I love banana and chocolate together (like this Chocolate Chip Banana Bread and Chocolate Chip Banana Bread Muffins. A delicious combo I must say.
So much goodness in these Banana Oatmeal Cookies, I wasn’t sure what to call them… Banana Oatmeal Chocolate Chip Cookies, Banana Chocolate Chip Walnut Oat Cookies, Loaded Oatmeal Cookies? Well whatever you want to call them, they are delicious.
I love bananas in my cookies BUT just like pumpkin, cookies with fresh ripe bananas can be overly soft and soggy. They can have such an overly gooey texture. I hate that!
I actually attempted these cookies a few times. One time did come out too soft and soggy, and another time the cookies came out extremely flat and kind of like florentines. Both were good in their own right but just wasn’t what I was going for.
There isn’t a huge amount of banana in these cookies. Just enough to get a little banana flavor without changing the consistency too much of the cookies. I actually based them a bit on my favorite and Best Chocolate Chip Cookie recipe.
Equipment You May Need
- Parchment Paper – Precut parchment paper sheets are not only great for easy cleanup but also helps prevent the cookies from sticking to the pan and over-browning on the bottom.
- Cookie Scoop – A medium cookie scoop (about 1 1/2 Tablespoon) helps the cookies come out in a uniform shape and size. And also helps speed up the cookie making.
- Baking Sheets – Good quality baking sheets can make a big difference when making cookies.

Banana Oatmeal Cookies Ingredients
- Flour – Regular all-purpose flour.
- Cornstarch – Just a little. I love adding cornstarch to cookies for a little different texture.
- Salt – Just a little.
- Baking Powder – To help the cookies rise.
- Baking Soda – To help the cookies rise.
- Butter – I used unsalted butter. If you only have salted, you can adjust the salt in the recipe. Be sure your butter is soft before making the cookies.
- Brown Sugar – Light brown sugar preferably BUT you could use dark brown sugar if you don’t mind more molasses flavor.
- Sugar – Regular granulated sugar.
- Egg – A large egg.
- Vanilla – A little vanilla extract either store-bought or homemade vanilla extract. Other extracts would ok too if you’d prefer.
- Banana – Make sure your banana is very ripe and soft. Mash it with the back of a fork until it’s mushy. You could also use banana baby food if you want. There’s not A LOT of banana in these cookies but it does give the cookies a nice subtle banana flavor. If you add more bananas the consistency of the cookies will change. You could also add a little banana extract for a stronger banana flavor.
- Oats – I used old-fashioned oats for this particular recipe.
- Chocolate Chips – Mini chocolate chips. Or you could use regular or even chopped chocolate.
- Walnuts – I toasted my walnuts first to give them a little more flavor, but you don’t have to do that. You can omit the nuts or use your favorite nuts such as chopped almonds, pecans, or even peanuts.

Serving Suggestions
- Serve at room temperature or even slightly warm.
- Place the cookies in the microwave or oven just to warm them up if you’d like them warm.
- Delicious with hot chocolate, coffee, or of course a big glass of milk.
Quick Tips for Best Results
- Make sure the banana is ripe. If the banana is under-ripe the cookies will not taste good. These cookies don’t have an overpowering banana flavor. You could add a little banana extract for a stronger banana flavor.
- Use good quality baking sheets, and be sure to rotate the pans halfway through the baking time so they bake evenly.
- Be careful to not over bake the cookies. They can go from soft to overly brown and crispy quickly.
- These cookies do not spread or flatten much so you can flatten them slightly with your hand before baking.
- If you do want to make larger or smaller cookies, you can use any size cookie scoop you’d like. Just be sure to adjust the baking time.

Thank you so much for this great recipe. My 4 year old daughter loves them for breakfast and snack. It’s the 2nd time we baked them and she had so much fun making the banana oatmeal cookies!
Awww thank you so much! So happy to hear your daughter likes them. :)
Made these today they are good and I like the thickness and texture
Great! Happy to hear you enjoyed!
These were just what I was looking for! A nutty banana chocolate chippity oatmeal cookie that is absolutely my favorite flavor- Chunky Monkey! Just wondering if a third banana would give it more flavor. What do you think?
Happy to hear you liked them! Another banana will probably change the texture of the cookie but could definitely try it. You could also mix in dried banana (like chopped up banana chips) or even banana extract. Hope that helps!
This looks amazing!
These are so amazing!! Thank you for sharing this recipe!
I’ve never tried banana in my oatmeal cookies before! These look delicious and I can’t wait to give them a try!
These look delicious! I am going to make some soon!
I’m all for a not-mushy banana cookie. Have you ever tried banana extract, though? I bought some a few months ago thinking it might enhance banana bread a bit. It tasted like banana flavored Laffy Taffy. I’ll bet there are some more natural tasting banana extracts out there, though.
Anna, funny you should mention banana extract! Just used it recently for some cupcakes, and you’re so right!
I only have quick oats which I use when I make Oatmeal cookies so I am going to bake this recipe even though it says use regular oats. hope they will turm out well.
Hope it turned out ok!
One of my childhood favorites. YUM!
I just happen to have a bunch of bananas sitting on my counter and I have been wondering what to do with them. These would be a great after school snack for my kids.
I’ve done peanut butter oatmeal cookies but not banana oatmeal! They sound so tasty! And those walnuts are a definite must for me!
These banana oatmeal cookies look so delicious! I’m always for adding chocolate chips to cookies and love that you did. I can’t wait to make these!
YES! I’ve been trying to make a good banana chocolate chip cookie for ages, but ran into the same issues you did. Pinned to try for sure!
These are wonderful! I don’t know why I never thought to do banana and oats together in a cookie, but I love this combination.
????I made these using raisins these are so amazing!, the 1/4 cup water is missing from ingredients in recipe.
